Fixing my bench light
HTML-код
- Опубликовано: 1 ноя 2023
- One of my bench lights started intermittently blinking off and on, and before it got too bad I decided to swap the driver in it, since it was the most likely issue.
If left longer the blinking would have got more frequent until the light was pulsing continuously.
If attempting a repair on a similar light, ensure the power is turned off and check the integrity of the earth/ground connection in the light. In this style of light you can use a lower power driver with a higher power LED. I use a 20W driver with a 50W LED.
My bench lights actually have a fairly easy life, since they are on a PIR sensor so that they turn on automatically when I approach the bench and turn off if I'm away from it for a few minutes.
It's hard finding a good quality driver with proper electrical noise filtering that actually fits in one of these floodlight cases. I opened a few lights, found a couple of suitable drivers and then chose the one that looked better quality.
The driver that failed is explored in another video.

This also keeps the channel independent of RUclips's algorithm quirks, allowing it to be a bit more dangerous and naughty.

This is proper telly.
Indeed !
Agreed. I decided years ago to cut the cable as the Cool Kids say, and have never regretted it. Our dear Clive has far better content, delivery, and production values than all of Hollywood and Bollywood combined. Besides, I love learning things and Clive is an excellent teacher. Why, just today I learned that I’m not the only one who forgets to remove that damned other screw I stashed before reassembling something that I’ve taken apart.
Presenters are supposed to be engaging. I prefer relatable, because engaging means manipulative. I can relate to Clive if for no other reason than the bandages on his fingers that appear randomly.
Television* aka TV*
The new season rocks so far.
Don't you mean, "This is proper RUclips?" (Which admittedly, you could watch on a Smart TV, but it would STILL be RUclips, and NOT TV).
No more flashing, neighbours must be relieved 😂😂 Good fix, thank you 👍
There's an image that won't go away.
@@MervynPinfield-rn4hs 😂😂🤣😂
Happy one million subscribers! You have been a big help in starting my electrical hobbies and I even learned to solder through your videos. Thank you so much.
Hey, when did that happen? I have never gotten into the habit of checking those numbers. I sub to channels that I like, not because they’re popular, so I didn’t notice an announcement.
Anyway, yes, congrats on hitting seven figures big guy, we all know it helps with the algorithm and you have certainty earned it.
Same here lol, been watching ever since!
Always fun to see something getting repaired rather than binned.
Thank you for reminding me I need to do something similar with my computer speakers (input wire has broken)!
It is not the case that you disregard safety.
It is the case that you are technically competent and understand the risks involved in what you are doing - irrespective of the fires and explosions that necessarily part of the fun of exploration!!
Well said Steve
Agreed, but still I admit to being a little bit disappointed when Clive doesn’t let the fire out of something (never mind the mere Magic Smoke others release) and we haven’t seen the hazard containment pie pan lately. I am maintaining hope though, since the revelation of the pyrotechnic potential of copper coated iron and aluminum wire. A man must have hope!
He doesn't _disregard_ safety, he entirely _regards_ it, and then carefully chooses which unsafe things to do anyway :)
BigClive is the Jack Hargreaves of modern tech. This is the good stuff we need more of.
OMG! You're right! Just without the wierd theme tune... A modern day sage.
Sorry, but I found Jack Hargreaves to be one of the most boring and monotonous presenters on TV, neither of which applies to Big Clive, who is both skilled and a pleasure to listen to.
@@MervynPartin entitled to your opinion.
I loved Jack Hargreaves. He was part of my childhood with "How" and. "Out of Town".
@@MervynPinfield-rn4hs A lot of his old programmes are here on RUclips.
Edit: Search for "Dave Knowles"
Some of the larger lights have space inside for a decent mains filter, and sometimes even enough space for a higher value electrolytic to help manage flicker. It might be worth it creating a small EDLC bank since supercaps have such an amazing energy storage, and the very minor discharge cycles would hardly affect their lifespan.
Clive, it would be really useful to see a video of your bench filming set-up. How you have the camera and lighting arranged, etc. We get snippets of elements such as the lighting on videos like this.
Studio tours are interesting to me in the abstract because I don’t plan on setting one up any time soon but yeah, I admit to being curious. Some RUclipsrs seem to work with their camera implanted n their head or chest while others constantly apologize for the awkwardness of them having to work around a camera they can’t see around.
I’m pretty sure Clive isn’t a cyborg but he never seems to have the camera-in-his-way issue.
He has mentioned that his available space is cramped and is therefore surrounded by constant threat of electronics avalanche, so it probably isn’t as neat and pristine as that of some RUclipsrs. I mean, AvE is a big fan.
I will admit that it's more than abstract to me, I have some close-up filming I need to do and I'm struggling to get the results that Clive and others (e.g. Davie McPhail) do due to there always seeming to be something in the way of me or something casting an awkward shadow or I keep misjudging what's in-shot. It's also the way Clive can say , "I'll just make an adjustment to the focus/exposure" and he just does it with no hint of a wobble or awkward reaching.
You jinxed me! One of my home lights started flickering (dead LED flicker).
It's the curse of modern lights.
@@bigclivedotcom I am now visualising a wizened old hag sitting by the packaging line somewhere in China, putting a curse on each unit as it goes into its box...
MeanWell does make high quality LED drivers, tho they're hard to find for the non-business clients. The easiest to find in my experience, is the AP series, but the 25W variant may be too big for your flood light enclosure.
Ooo, a cliffhanger episode. Definitely some good telly.
I like the use of side cutters for wire stripping. I did work with a guy once who used to go absolutely mental if he caught anyone doing such a heinous thing instead of using a proper (very expensive) wire stripper.
Admittedly on some PTFE insulated wire types, a proper stripper makes all the difference.
yeah I only use my flush cutters for stripping wire. anyone I've worked with who's actually stripped a lot of wire hasn't had any issue with my tool choice, though. management and the one guy who made one off prototype wiring harnesses did, though.
@BigClive, it looks like you hit 1,000,000! Congratulations!
For some reason last night I was watching all of your flood light videos 😂😂😂 how coincidental
Hey BC....was at a lunch yesterday with some former colleagues - bunch of sad ex-BBC engineers. You name came up. You know you've 'arrived' when a table of BBC engineers know your name :)
Didn't Clive work on a few BBC projects over the years?
A pile of potting compound now hints at wonders to come!❤
That's the next video.
🎉
Constant current power supplies are harder to find but there are some available locally. The manufacturers of electronic ballasts for fluorescent tubes are now making LED drivers as well.
Thanks Clive very illuminating. At least the power supply lasted longer than the guarantee.
Very illuminating video!
Fumblesome is my new favourite word.
Think I'll call my boyfriend that.
"Oh sweetie, you are so fumblsome".
I don’t often comment, but I have learned so much from your content over the years.
I remember it failing during the custom bulb video and you mentioned "might need to replace the driver "
Hey Clive, if you want more intense light, you should work with live wires like Mehdi ElectroBOOM does. That should be quite the intense experience.
Not sure if it's just my eyes being weird, but the repaired light seems to be less intense than the left-hand light, could just be positioning of the light or something, but, it does seem a bit "off" somehow, still, better than being a blinky nuisance anyway, one of the joys of "affordable" LED lighting these days, going from useful light to disco strobe... :P
I'm glad you mentioned the low quality electric wire. One thing that I run into is people using copper coated steel wire for their off-grid solar systems and wonder why they perform so poorly......
Big Clive. Could you possibly include a view and description of your work bench area and lighting positioning in one of your videos. My 12V LED bench lights have recently failed so I'm looking for a suitable replacement. Cheers.
Just out of curiosity a "behind the scenes" type video showing the setup would definitely be interesting.
I liked the temporary light way more than the one you fixed because the color looks warmer
while the one you fixed is too much bright and cold.
Great video BTW.
Quite possibly his lights are overkill especially if you are still on B&w lol
ONE MILLION subscribers ❗❗❗
Congrats Big Clive 😁👍
Thanks for taking the time to show us your exploits.
This is the Big Clive version of Trigger’s broom.
Genuinely enjoyable video, the quick practical repair helps me justify my hoarding of electrical components Cheers!
Yeah, the only problem is now I need to stop watching internet videos so I can actually go work on all of my own broken things... :)
Same, I am a pack rat when it comes to electrical stuff. I just recently bit the bullet and donated a lot of it to Habitat For Humanity. Now I actually have a few empty shelves in my shed, a condition that won't last long.
"Clone cables and clone terminals, that's a perfect combination" - I can't disagree, this seems just wholesome.
The temporary lighting was certainly a lot warmer looking. Now your hands have become British Ultra White again!
Nice to see you spread some light over the issue you had Clive ;)
I hope you have children, I wouldn't want that level of hunour to go wasted. :)
@@twotone3070 sorry to break it to you but I am all alone
One of the best reasons to turn a newly fixed light upside down is not to get blinded by the high-power LED.
Also:
To keep the shrapnel safely inside if the "new" power supply decides to loose a few components on power-up.
Hence my motto: "Red on red, Black on black and STAND BACK!" 💥💥💥
Your videos helps a lot of people from difference backgrounds to get started, keep up the good work Clive!
Handy tip , the ( last few working ! ) tiny 4 Volt Tungsten filament bulbs from a defunct light string can be reused as individual bulbs with 6 inch added tails .. as single cell battery testers ! ! ( 1v5 or 3v7 ) ... these have the advantage of drawing a good current , like the meter types , but NOT suitable to test button or coin cells , as they draw too much current , ideal for storing in any kitchen drawer for easy instant use ! ... ( tried - n - tested ) ..... DAVE™ 🛑
Mr Clive, I like it when you repair certain things, I haven't done it for a while, that part of the program I haven't left for a long time.
Awesome Video Big Clive and i am glad that you were able to fix your light.
Now THAT was a FUN video! Love your repair videos. 😀
Brilliant Clive thanks can’t wait to see the insides 😊
Congratulations on one million subscribers. You deserve to have more. I still think you should do audio book narration, lovely to listen to your soothing tones. Take care of yourself.
My kitchen has been lit by around 500 Cool White LEDs since 2012 ... I converted the 5-foot fluorescent fixture to LED ... Works as good as the day it was new, 11 years ago!
Good to see that you got your lighting fixed, and also that you can buy fittings with removable PSUs! I have had so many different outdoor floodlights (for lighting the front and rear gardens) fail, where I believe the LED has been fine but the PSU has failed, and in true LED fashion the PSU is not easily accessible by the end user and therefore cannot be replaced!
Looking forward to part 2.
Nice hack. Good luck with the new driver! :)
Thanks again for another repair rather than junk video. We as your RUclips followers value the light!
Ending on a cliffhanger, what a tease you are ......... ;-)
That video will be out soon.
Hi Clive. Great video as ever. I'd recommend Ct1 Multi solve to remove silicone safely. 👍
I'm surprised you weren't able to find an appropriate LED driver from the usual trusted vendors. Although lately I've found they have less options available in stock, and it's usually the more expensive options that are stocked. And sometimes you can't even trust that they've actually got the stock they say they've got. The last two times I ordered from the silicon-based electronics supplier, everything was supposedly in stock when I checked out, but then I got an email saying it's going to be weeks to months wait on stock.
I was caught short. I thought I had spare drivers but couldn't find them.
Herzlichen Glückwunsch zu eine Millionen Abos💐!
Gute Videos 👍🏻
Congratulations on 1M! :D
Congrats on the 1m subs Clive!
Happy One illion Clive. A very interesting channel you have there.
Nice job and thanks Big Clive. It's very satisifying to improve one's lighting. A fairly simple fix and good results. High CRI units are the way to go. I just ordered a couple of LED power supplies from Ali. Hopefully they're decent.
"Fumblesome" is my new favorite word
Great video Clive thanks
My suggestion would be a MEAN WELL power supply, they are great (but expensive), I love your WERA screwdriver (my favorite).
Yay! A repair video!
I have something very similar Clive. A 100w LED driven at about 80w. I'm using a 24v 10a supply with a current limited boost converter. I've got it slapped on an old CPU cooler with a simple temperature controlled fan controller. It's retinadestroytastic!
Mean Well makes really good quality LED power supplies for a reasonable price.
Like a proper gaming chair for some we now know the secret of Clive's success: the bench light.
Nice, well done ☺
Good morning from the cheep seats.
I've repaired so many of the Chinese specials Clive and hate throwing things away too. You're very lucky if you find an earth to the chasis too..
I use vintage clamp on drafting table lamps retrofitted with LED bulbs. Gives tons of moveable light. Future plans are Snap-Loc hose and LED fixtures but gonna wait till current setup dies. Might be waiting 100,000 hours.
The answer to the dearth of quality power supplies is to devote a future video to constructing your own! Perhaps an old fashioned type with a proper chunky transformer..😛
A very good result :)
I spent yesterday replacing the LED in a 10 Watt lamp, then I find this video,
Perfect timing
Yay for fixing things!
Good. I need simple stuff first thing in the morning !
They made sure the power supply was not fixable and was therefore a throw away unit. I like the deformable garage lights that has 3 or 4 adjustable vanes that can shine light anywhere as they move in all plains.
In all "plains"? The ones where the buffalo roam?? I bet the buffalo really hate LED shop lights on their plains - makes it hard to sleep
LOL@@gorak9000
@@gorak9000 I don't see them complaining about the big nuclear light bulb in the sky. They can get used to a wee LED light in the night. Honestly buffalos these days have become a bunch of sissies 😒
The potting isn't anti-repair, it's anti-moisture
You repair it.@@_BangDroid_
Interesting to see ❤
I had the same concept but a 70W fixture and it would blink. I also changed the PS and it still blinked. I've had several chips do that. It turns out that the internal bonding that supplies all the strips in the chip (s) acts like an old fashioned tungsten bi-metal blinking strip. On this particular chip that had a round 70W chip I used a square 100W chip and drive it with a 70W supply like that. The case is the heatsink and it's poorly designed with pop metal that doesn't transfer/dissipate heat very well. It's been 8 months now and it's still working fine.
The most common failure in these LEDs seems to be where the bonds go onto the busbar at one end.
More interesting and more informative than 99.99% of the dross on TV. Really appreciate your videos.
I wonder if ferrules would help with the mains wires? They're not strictly necessary with wago style connectors, but they're really useful with thin wires.
I would like more videos about matching powersupply with LEDS.
Create your own power supply to drive your LED? It would be an interesting video.
@BigClive, I’ve enjoyed your channel for years. I have a question that I haven’t been able to find an answer to, and it seems right down your alley. Why do touch lamps of many types always become over-sensitive? For a while a short term fix seems to be opening the circuit (switching the lamp off, unplugging, or removing the screw-in circuit). Is it for lack of a ground connection to the control circuit?
This is pretty important to me because I have a degenerative nerve disease, and often cannot use a physical switch. Thank you for anything your genius can shed light upon!
It could be due to a bad ground, or perhaps adjacent electrically noisy equipment (possibly an LED bulb).
Aww, I was hoping you'd swap out for a pink LED. 😂
I know what you mean about paying more for the same or worse quality Clive .. I needed to replace a floodlight at our back door, so rather than hit the Chinese sellers, I paid royally for one from a Retail Lighting Shop .... took it home, wired it up .. DOA ..... closer look at it found the same old floating Earth, poor quality build etc. I am sure it was the same rubbish in a shiny box !
one thing i'd recommend to check out for these flood lights is the replacement led modules with 10 Cree XML's on them (for a 100W one)
these old style COB leds are all pretty inefficient, in my opinion atleast, i believe they're at like 60lm/W
the Cree's (even the cheap T6's) produce almost 100lm/W, so yea those are pretty good
they also exist with XP-E leds etc. in 30W and whatnot
haha your light must of been so upset when denied a custom bulb, funny stuff haha!
If you're willing to spend a little bit more, Meanwell makes a whole ton of different kinds of LED drivers for every combination of current, voltage, ratings, dimming, and any other possible parameter you could want. I've used all kinds of their supplies (including constant-current and constant-voltage LED drivers) and have not had a single issue, after getting fed up with all kinds of cheap clone supplies dying just like you show here.
Something like the 20W you're looking to drive will probably set you back $20-50 depending on how fancy you want your features, which is honestly a small price to pay for something that will never fail again.
You should run Meanwell or similar power supplies. But then again, they wouldn't provide any exciting failure and dissecting video opportunities.
Anything that tends to get warm and degrade w/ heat, I usually try to cool in some way.
Either with it's own power (+ a pot sometimes) or even a microcontroller in some cases
CCA cable has it's issues so it's stealthily being replaced with copper covered iron which solders better but has different current capacity, and flies to magnets.
Nice video. Maybe the only way these days to get a good power supply is to make it yourself.....
Still, makes for a good video when cheap ones go wrong.
Your light sounds like Trigger's broom there mate!
It is.
You love to see it.
Looks like the AVE hammer surgically opened that power supply :)
Along the lines of having a flock of solder or a stray blob of solder.
I've seen this wreak havoc in devices.
This is the most recent thing I've seen that had a problem with something wrong with this lines.
In this case there was actually two little splashes of solder on the inside.
I had one of those side socket sort of USB equipped surge protectors.
Had both to USB a force and a USB C port.
First thing that went out was the USBC then finally the rest of it which was kind of strange but then again I haven't unplugging it and using it elsewhere moving around turns out that what killed it was both the USBC Port first and the other was flex and drops of solder that had been there for manufacturer that broke loose from the plastic chassis and floating around in there and of course hitting something critical shorting something out and of course doing the deed.
Also something of Interest this might appeal to viewers of this channel as well.
On that particular surge protector what was used as the protection indicator was essentially a LED and a resistor wire across the output of the power supply for the USB thus win The Surge protection is no longer functioning which also this one didn't have the thermal fuses which completely cut out the output in series with the supply to both the receptacles and also USB power supply module which looks like an off-the-shelf module by the way!
Very interesting design very well-built if it weren't for the Solar Supply is it would still have been working to this day.
So definitely something to avoid when you're building something for yourself and also in manufacturer but you know something's always have a tendency to slip past quality control or like oh it'll be okay sort of thing well not in this case!
Use it for quite a few years!
Served very well until that time really high quality it seems like the wiring on the AC side of things is heavier than needed to be even.
And yeah designed for the US market it was pretty clever how things were done in there with the ability to swivel the three AC sockets and the three USB as well.
I was expecting it to be contacts either side however something better they had just run the power wiring through one end each of the two separate sections definitely better than some of those funky contacts that sometimes don't work well I've seen these fail on something similar.
But then again somebody was putting a pretty heavy load on these and they were discolored so clearly High Resistance connections but not surprising probably due to tensioner that was contacts I think it was an earlier design the name is something that had been Don similar to the above surge protector later on since I saw the same product essentially but don't know if it's the same brand and haven't done with just wire going from the main body to the swiveling sections so likely the design change because of reliability and other issues
Couple of observations, the potting, is probably the cheapest way to hide shoddy work, at least with the heat shrunk unit you could fix it if it starts to mess around, I worked in high spec power supply company years ago, and the only supplies we would pot were HT supplies for use at altitude, some of the testing was interesting the first couple of times you do it, after the first 20 or so, it wasn't so exciting. My first exposure to flourinert, putting a seriously high voltage into what looks like water, then putting test probes on while live was disconcerting at first, the test manager put his finger in with a running 25KV supply, i was convinced after that.
Secondly, how can it be cheaper to produce copper plated cable then pure copper cable? Maybe it's the sad fact that their labour rates are so low?
I have a bunch of meanwell 12v 16 amp power supplies going spare. I'll have to send you a few.
Oh great, Febreeze ads. I place the blame fully upon you, Clive.
dude, wtf, do you live under a rock? u block origin
It's crazy, my bench lighting just started doing this on/off every few seconds too. It's a 10W COB and a 10W driver like these. I bought new ones from Ali a while ago but it got refunded. The seller didn't respond in time or something.
I like to use Meanwell constant current drivers for my COBs over my workbenches. They are actually not that expensive.
They still do Clive one of the best is put them right next to a heatsink on a power supply 😮
Clive' s been Nibbling & Stripping once again.
Old habits n all that 😉😀
There was a 13% chance red wouldn't be the positive wire ;)
Lucky Clive.
I have the same lamp outside in the shed and replaced the led four or five times already. Three times this year. They are very cheap, 1-2 dollars, but die fast.
The case is often not really rated to dissipate enough heat. The LEDs sold on eBay are often substandard ones being "dumped".
